feat: 卡流量读数先过采集队列再入账，扣减按采集时刻确定套餐

- 每卡 Redis 采集队列（默认 N=3、跨天清空、回退容差 1 MB），攒满且不下降才写最后一个点
- 测试环境全量切换日快照计量，下线灰度名单、切换水位与卡表基线扣费；全部卡置待建起点
- 读数区分没给值与 0；有套餐的卡读数 0 也写快照与日用量 0 行；重置日比较基准为 0 照常防旧值
- 新增采集记录（按月分区保留 90 天）、人工冲正流水与后台接口、采集告警
- 扣减按采集时刻有效套餐查找，只对生效中套餐做状态迁移，查不到套餐按成功跳过
- 换货新卡（新设备下的卡）打待建起点；采集间隔上限只校验启用中的轮询配置
